AUTOMATIC LAOlNG-HOOK-SETTING MACHINE.

Specification of Letters Patent.

Patented June 4;, 1907.

Application filed December 18,1905. Serial No. 292.273.

To (all 'II/7l/0777/ it may concern:

Be it known that we, WILLIAM P. BARTEL, residing at IValtham, and SYDNEY E. TAFT, residing at South Framingham, in the county of Middlesex, State of Massachusetts, have invented new and useful Improvements in Automatic LacingHook-Setting Machines, of which the following is a specification.

This invention relates to a machine for attaching lacing hooks to the uppers of boots and shoes, the object of the invention being to provide a machine which may be run at a high rate of speed and attach lacing hooks to the uppers of boots and shoes at equal distances apart without the operator being obliged to do anything more than to insert the leather upper in the machine and hold the edge of it against a gage while the machine inserts the lacing hooks and feeds the upper the required distance between said hooks.

The object of the invention is further to provide a machine of the class hereinbefore described which is strong, durable andcheap in construction and in which provision is made to eject hooks which may be driven, when no upper is in the machine, through the carelessness of the operator in not inserting such upper or in not properly managing the treadle by means of which the machine is controlled.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a plan view of our improved machine for setting lacing hooks, the clutch being shown in section. Fig. 2 is an elevation of the same from the right hand side of Fig. 1, the same being shown partly broken away and in section. Fig. 3 is an elevation of the same as viewed from the left of Fig. 1. Fig. 4 is a plan view, enlarged, with certain of the parts broken away and shown in section, of portions of. the hook feeding and carrying mechanism, showing the parts in the positions which they occupy when the hook is being set. Fig. 4 is a detail plan of one of the feed dogs. Fig. 5 is a plan view, similar to Fig. 4, showing the parts in different relative positions, with the carrier rocked backwardly to clear the lacing hook and starting downwardly. Fig. 6 is a Fig. 2. Fig. 7 is a section, partly in plan, taken on line 77 of Fig. 2. Fig. 8 is a section, partly in elevation, taken on line 88 of Fig. 10, and illustrating the manner in which the lacing hook is held upon the upper end of the carrier. Fig. 9 is a detail front elevation of a portion of the work-support with the hook-positioning plate attached thereto. Fig. 10 is a plan view of the resser foot, work-support and lacing hoo carrier or plunger. Fig. 1 1 is a section, artly in elevation, taken on line 11-11 of ig. 4. Fig. 12 is a front elevation of the presser foot, anvil and feed point and the upper portion of the plunger or hook carrier, with the presser foot down and the anvil and feed point having fed the material to its extreme forward point or to the extreme left, as viewed from the front of the machine. Fig. 13 is a view similar to Fig. 12, with the anvil moved upwardly and backwardly from the position shown in Fig. 12. Fig. 14 is a View similar to Figs. 12 and 13, with the feed point just entering the material in readiness to feed said material. Fig. 15 is a View illustrating the presser foot raised and the material being fed by the feed point and anvil.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, the lacing hooks are placed in a hopper supported upon the frame 2 1. In the interior of the hopper 20 is a picker plate 22, to which an intermittent rotary motion is imparted, as hereinafter described, by which the lacing hooks are fed in a manner well known to those skilled in this art to a stationary raceway 23 formed in two parts 24 and 25, with a passageway 26 between their adjacent edges. The raceway -23 is bent at its lower end so that the parts 24 and extend in a horizontal instead of a vertical plane, the part 24 extending beyond the part 25 at the lower end of said raceway, as seen in Figs. 4 and 5.

The lacing hooks 27 slide down the raceway 24 until the lowermost hook 28 upon said raceway comes to a rest against the spring stop 29 fast to the part 24 of the raceway 23. Said lowermost hook is fed ositively past the spring stop 29 by one of the rotary feed dogs 30, 30. Said rotary feed dogs are each pivoted at 31 to a collar 32 rigsection, partly in plan, taken on line 66 of i idly fastened to a vertical shaft 33 journaled IuO to rock in bearings in the frame 21, (see Fig. 2.) Each of the feed dogs, as illustrated in Figs. 4 and 4, consists of a flat piece of steel with a projecting tooth 34 formed upon its outer or free end, anda pin 35 fast to said feed dog and projecting upwardly therefrom through a slot 36 formed in a cap-plate 37 which is fastened by screws 38 to the collar 32, said cap-pl ate being, in effect, an integral part of the collar 32. The four feed dogs 30 are held with their teeth 34 projecting be yond the periphery of the collar 32 and capplate 37 by spiral springs 39 which rest in recesses 40 between the cap-plate 37 and the collar 32. The pins 35 limit the distance to which the springs 39 can force the teeth 34 of the feed dogs outwardly. An intermittent rotary Irfotion is imparted to said feed dogs, to the collar 32, to the cap plate 37 and shaft 33 by a pawl 41 (Figs. 2 and- 5) which engages teeth 42 formed upon the lower end of the shaft 33. Said pawl is pivoted to an arm 43 formed upon a pinion 44 which is journaled to rock loosely upon the shaft 33 andmeshes into a segment gear lever 45.

\ The segment gear lever 45 is pivoted to a stud 46 fast to the frame of the machine and has a rocking motion imparted thereto by a rod 47, which is constructed to slide at one end thereof (Fig. 1) in a bearing 48 fast to the frame of the machine, and at the other end thereof is fastened to a cam-slide 49, slotted to straddle the main driving shaft 50. A

cam roll 51, rotatably mounted upon said cam slide 49, projects into a cam groove formed in the cam 52, by which cam a reciprocatory motion is imparted to the slide 49 and slide-rod 47. The front end of the slide rod 47 projects through a slot 53 formed in the head 54 of a stud 55 (Fig. 11). The stud 55 is supported upon and is free to rock in the outer end of the arm 56 of the segment lever 45.

A guide-plate 57 (Figs. 4 and 5) is fast to the frame of the machine and to the lower end of the part 25 of the raceway. The lower end of said part 25 is formed upon a concave curve adjacent to the periphery of the collar 32 and the guide-plate 57 has an inclined face 58 adjacent to the periphery of said collar, so that as said collar is rotated the outer end of the tooth 34 of each dog, as it passes the incline 58, is forced inwardly and slides along said inclined face and along the edge of the lower end of the raceway part 25, passing between the lacing hooks 27 and 28 until released from said raceway when it snaps in between said lacing hooks, being forced outwardly by one of the springs 39. The lowermost lacing hook located in the position of the lacing hook 28 (Fig. 4) is then positively carried around the curved lower end of the raceway part 24 and onto a plate 59 (Figs. 4, 5 and 8). The plate 59 is rigidly fastened by a screw 60 and dowel-pin 61 to rier.

the top or head of a carrier 62. The carrier '62 and the plate 59 are thus fastened firmly together and form in effect and function a single piece. Said carrier is provided with a recess 63 adapted to receive the head 64 of a lacing hook, and the plate 59 is cut away at 65 to form an outlet passage for the head of the lacing hook to pass through when it is removed from the carrier, as hereinafter described. It will be noted that the outlet passage 65 is adjacent to the recess 63, being located immediately thereabove and leads therefrom out of the upper end of said ear The carrier 62 is rotatably mounted in a sleeve 66 arranged to slide longitudinally thereof in bearings 67, 67 formed in the frame 21. Said carrier has a stem 68 fast to the lower end thereof and extending downwardly therefrom through a collar 69, said collar being held upon said stem by means of a cross-pin 70 (see Figs. 2 and 7). A torsional spring 71 encircles the stem 68, its upper end being fastened to the carrier 62 and its lower end being fastened to the collar 69:

More or less tension may be imparted to said spring by rotating the collar 69 upon the stem 68, and when said spring has been wound to the necessary degree of tension the collar 69 is fastenedto the sleeve 66 by a screw 72 having screw-threaded engagement with said sleeve and projecting into one of the recesses 73 formed in the periphery of said collar.

In the upper end of the sleeve 66 is a screw 74 having screw-threaded engagement with said sleeve and projecting into an annular slot 75 formed in the periphery of the carrier 62 Fig. 6. The object of this slot is to allow the carrier to be rotated upon the sleeve without the sleeve rotating, or to allow the sleeve to rotate without the carrier necessarily being rotated thereby. There are two cases in which this relative rotation of the sleeve to the carrier is necessary. In the operation of the machine the sleeve is rotated by suitable mechanism, as hereinafter described, from the position shown in Fig. 4 to that shown in Fig. 5 and back again, and when it is rotated to the position shown in Fig. 4 from the position shown in Fig. 5, it is essential. that the straight edge 76 of the plate 59 should abut against the corresponding straight edge at the lower end of the race way part 24, so that said plate forms, in effect, a continuation of the raceway part 24 when the parts are in the position illustrated in Fig. 4, and the lacing hook is fed from said raceway onto said plate. In order that said plate should not be brought against the raceway with a hard blow and also in order that the accuracy of the mechanism by which the sleeve is rotated should not be necessarily too great, the torsional spring 71 yields after the straight edge 76 of the plate 59 comes in. contact with said raceway part 24, thus allowing the sleeve 66 to move slightly in the direction of the arrow a (Fig. 6) after the plate 59 has come into contact with the raceway part 24, in which case the inner end of the screw 74 moves around a slight distance in the slot 75, the torsional spring yielding to allow of such relative movement between the sleeve and carrier. The other case in which it is necessary that the carrier should be rotated relatively to the sleeve occurs when a lacing hook 77 (Fig. 4) becomes jammed upon the plate 59 or in the lower end of the raceway, in which case the carrier is rotated, by means of the handle 7 8,from the position illustrated in Fig. 4 to that illustrated in Fig. 5, and the hook can then be removed and drops down through the outlet passage and recess 63 and out of the machine, the frame being cut away at 79 (Fig. 3) to allow said hook to drop out of the machine.

The sleeve 66 is rotatably mounted upon a spindle 80 and is prevented from longitudinal movement upon said spindle by a shoulder 81 formed upon said spindle and projecting beneath the lower end of the sleeve, while a screw 82 which fastens a pinion 83 to said sleeve prevents said sleeve from moving in the opposite direction longitudinally of said spindle. A rotary motion is imparted to the sleeve 66 by said pinion 83 and by the seg ment lever 45 which meshes thereinto. The spindle 80, sleeve 66 and carrier 62 form, as a whole, a plunger, to which a reciprocatory motion is imparted by means of a togglejoint consisting of two links 84 and 85 and. a cam-slide 86 (Fig. 3). The links 84 and 85 are pivotally connected at 87 to said camslide, the link 84 being pivoted at its upper end at 88 to the lower end of the spindle 80. The link 85 is pivoted at 89 to the base 137.

The cam-slide 86 is formed in two parts, viz., a rod 90 and a slide plate 91 rigidly fastened together. The slide plate 91 is slotted at 92 and has sliding engagement with a block 93 pivoted upon the main shaft 50. A cam roll 94 is rotatably mounted upon the cam slide plate 91 and projects into a cam groove formed in the cam 95, whereby a re ciprocatory motion is imparted to the cam slide 86 and a reciprocatory motion thus imparted, through the toggle links 84 and 85, to the plunger 96. The sleeve 66 and the carrier 62 are rocked by the segment lever 45.

The material 97 or shoe upper, into which the lacing hooks are to be set, rests upon a work-support 98 fast to the frame of the machine, and said material 97 is fed along the upper surface of said work-support by a feed point 99 projecting below the clenching surface of an anvil 100. The anvil 100 is adjustably fastened to an anvil carrier frame 101. The carrier frame 101 consists of a vertical shaft 102 constructed to slide in bearings 103, 104 formed upon the frame of the machine, and an arm 105 rigidly fastened to said shaft. The anvil 100 has screw-threaded adjustment in and is supported directly upon the arm 105, to which it is clamped by a screw 106. A vertical motion is imparted to the carrier frame 101 by a cam lever 107 pivoted at 108 to the frame of the machine and having rotatably mounted thereon a cam roll 109 which engages a cam 110. The cam lever 107 is connected to the shaft 102 by a screw 111 fast to a collar 114. Said cam lever is bifurcated at the right hand end thereof (Figs. 2 and 3). Each arm of said bifurcated end has a slot 113 formed therein and in each of said slots is located a sliding block 112. Each of said screws 111 is fast to the collar 114 and extends through one of said sliding blocks so that the same are free to rock thereon. The collar 114 is loosely mounted upon the shaft 102, so that said shaft is free to rock in said collar and said collar is prevented from longitudinal motion upon said shaft by means of a collar 115 fast to said shaft above said collar 114 and by a washer 116 fast to the lower end of the shaft 102. It will, therefore, be seen that the shaft 102 can be moved vertically in the bearings 103 and 104, while at the same time it may be rocked in said bearings, and this rocking motion is imparted to the shaft 102 and to the arm 105 by aslide 117 arranged to slide in bearings 118, 119 formed upon the frame 21 (Fig. 2). The front end of said slide 117, or the left hand end (Fig. 2) is slotted at 120 to receive a sliding block 121 which is rotatably mounted upon a stud 122 fast to an arm 123 which is integral with the arm 105. A reciprocatory motion is imparted to the slide 1 17 by a link 124, pivotally connected at one end thereof to said slide and at the other end to a stud 126. The stud 126 may be clamped by the handle nut 127 to a lever 128, said stud projecting through a curved slot 129 concentric with the center of the pivot 125.

The lever 128 is pivoted at 130 to the frame 21 and has a rocking motion imparted I thereto by a cam slide 131 actuated by a cam 132 fast to the main shaft 50, said cam slide being pivotally connected to the lower end of the lever 128.

A presser foot 133 is fastened to a vertical rod 134 (Fig. 3) adapted to slide in a bearing 135 formed in the frame 21 and in a bearing 136 formed in the base 137, and having a collar 138 fast thereto intermediate said bearings 135 and 136. A spring 139 encircles the rod 134 and holds said presser foot normally pressed against the upper surface of the work-support 98. The presser foot is raised away from the work-support by means of a lever 140 pivoted at 141 to "the frame of the machine and having a cam roll 142 rotatably supported thereon and bearing against the periphery of the cam 110. The right hand end of the lever 140 (Fig. 3) bears against the under side of the collar 138 and the cam 110 IIO &

is provided upon its periphery with a rise or open cam 143, whereby, in the rotation of the machine, the presser foot is at certain intervals in the cycle of operations raised by the cam away from the work-support for the purpose of allowing the upper to be fed, as hereinafter described. If the operator desires to raise the presser foot independent of the rotation of the machine, in order to insert or to remove an upper therefrom, he presses upon a treadle (not shown in the drawings) connected by a rod 144 and hook 145 to the lever 140.

The work-support 98 is provided with a groove 149 in its upper surface into which the feed point 99 projects as the upper is being fed, said groove 149 being concentric with the center of the vertical shaft 102 to which the arm 105, carrying the feed point 99 and anvil 100, are fastened. The upper is guided by holding the front edge thereof against an edge gage 150, said edge gage being provided with a slot 151 through which a clamp screw 152 projects, said clampscrew 152 having screw-threaded engagement with the worksupport 98, whereby said edge gage may be adjusted relatively to the feed point and plunger.

A rotary motion is imparted to the main driving shaft 50 by a clutch 153, consisting of a pulley 154 (Fig. 1) journaled to rotate loosely upon the main shaft 50 and adapted to be engaged by a friction clutch pulley 155. Said friction clutch pulley is splined to the shaft 50, so that it may move longitudinally thereof, but is locked thereto with relation to rotary movement. Said clutch pulley is provided upon its periphery with two oppositely inclined conical surfaces 156 and 157. The surface 156 is adapted to engage a like conical surface formed upon the interior of the pulley 154, while the conical surface 157 is adapted to engage a like surface formed upon the interior of a brake 158 fast to the bed of the machine. It will be seen that when the clutch pulley is in contact with the pulley 154, the shaft 50 will be rotated and when said clutch pulley is in contact with the brake 158 the machine will be stopped.

In order that the rotation of the machine shall always be stopped at a certain point in its rotation, thus always stopping the machine with the parts in the proper position to remove an upper which has had lacing hooks inserted therein and to insert an upper to which lacing hooks are to be attached, a cam 159 is provided upon the periphery of the cam 132, which is adapted to impart a rock ing movement to the lever 160 pivoted at 1.61 to the base 137 and this lever has pivoted thereto a link 162 which is connected by a rod 163 to a treadle (not shown in the drawings). As long as the operator holds his foot upon the treadle, the link 162 is out of ahnement with the adjustable screw 164, but when said treadle is released a spring pushes the rod 163 upwardly, causing the right hand end of the link 162 to be raised (Fig. 1) into alinement with the screw 164, and upon the rotation of the cam 159 said link 162 pushes the screw 164 toward the right (Fig. 1). The screw 164 is fastened to an arm 165 which, in turn, is fastened to a rock-shaft 166 jour naled to rock in bearings 167, 168 upon the base 137 (Fig. 2). Another rocker arm 169 is fastened to the rock-shaft 166 and engages at its upper end an annular ring 170 which fits in a corresponding groove 171 formed in the hub of the clutch pulley 155, so that when the link 162 pushes the screw 164 toward the right (Fig. 1), as hereinbefore described, the clutch pulley 155 will be moved toward the right out of contact with the driving pulley 154 and into contact with the brake 158, thus stopping the machine at a certain point in the rotation of the shaft. When the operator places his foot upon the clutch treadle again, the link 162 is drawn out of alinement with the screw 164 and a spiral spring 172 forces the clutch pulley 155 out of engagement with the brake 158 and into engagement with the pulley 154, thus starting the machine. The s ring 17 2 bears at one end against thehub of the pulley 155 and at the other end against a washer 173 which is held upon the shaft 50 by a nut 174.

In machines of the class to which this invention belongs, it is essential, in order that the machine may be run at high speed, that the picker plate should be fed forward as slowly as possible in order not to throw the hooks and injure the same in the hopper. To secure this result a pawl and ratchet mechanism is employed for the rotation of the shaft to which the picker plate is attachedf and a slow forward and a quick return movement is imparted to said pawl. The mechanism by which this differential movement is imparted to the pawl is as fol lows: A gear 175 is fastened to the main driving shaft 50 and meshes into a gear 176 which drives a shaft 177 (Fig. 1) journaled to rotate in a bearing 178 and having fastened thereto a pulley 179 which is connected by a belt 180 to a pulley 181. The pulley 181 is fastened to a shaft 182, which has fastened thereto, at the opposite end thereof from that to which said pulley is attached, a crank 183,

- said crank having a crank-pin 184 fast thereto and projecting into a slot 185 which extends longitudinally of a pawl lever 186, said pawl lever pivoted to rock upon a shaft 187 to which the picker plate 22 is fastened. The shaft 187 is journaled to rotate in a bearing 188 in the hopper 20 (Fig. 1). A pawl 189 (Fig. 2) is pivoted to the pawl lever 186 and engages th teeth of the ratchet 190, said ratchet being rigidly fastened to the picker shaft 187.

It will be seen that as the shaft 50 rotates, the gears 175 and 176 will rotate and thus drive the pulley 179, belt 180 and pulley 181, rotating the shaft 182 and the crank and crank-pin 183 and 184, respectively, in the direction of the arrow 1) (Fig. 2). As the crank-pin 184 is rotated it moves longitudinally of the slot 185 and thus alternately approaches and recedes from the shaft 187, upon which the lever 186 is rocked. It will, therefore, be seen that as the crank-pin approaches the center of the shaft 187 the an gular velocity of movement of the lever 186 will increase, and as said crank-pin recedes from the shaft 187 said angular velocity will decrease. when the crank-pin184 is farthest removed from the shaft 187, the lever 186 is rocking in the direction of the arrow 0 (Fig. 2), and when the crank-pin 184 is nearest to the shaft 187, said lever is rocking in the opposite direction to that of the arrow 0 (Fig. 2). It will, therefore, be seen that when the pawl 189 is driving the ratchet 190, a slow movement is being imparted to said pawl and ratchet, to the shaft 187 and to the picker plate 22, and when said pawl is moved backwardly over the teeth of the ratchet a quick movement is being imparted to said pawl. It will be noted that the means by which a rotary motion is imparted to the crank 183, viz, the pulleys 179 and 181 and the belt 180, constitute a frictional means driven by mechanism operated by the main shaft, viz, the gears 176 and 175, the object of this frictional mechanism being that if any of the hooks become jammed between the rotary icker plate and the hop er, the belt will sip upon the pulleys witliout driving said picker plate and injuring the hooks and picker late itself.

The fiook separating mechanism hereinbefore described is substantially the same as that set forth in a co-pending application for Letters Patent made by us, Serial N 0. 292,274, Hook separating mechanism, filed Dec. 18, 1905.

In order to hold the lacing hook 77 firmly in position upon the carrier plate 59, a slide 192 is provided which is dovetailed to slide in the top of the work-support 98 and has a downwardly projecting lip l 93 (Figs. 8 and 9). A spiral spring 194 is located in a recess 195 formed in the work-support 98, one end of said spiral spring bearing against said work-, support-and the other against the inner face of the lip 193, thus forcing said slide 192 toward the carrier 62. The lower end of the outer face of the lip 193 is beveled at 196, so that as the carrier rises, as hereinafter described, with the hook upon the plate 59, the neck of the hook 77 comes in contact with the inclined front face of the lip 193, and said lip bearing against the neck of the lacing hook holds said lacing hook firmly in position upon the plate 59 as the lacing hook is being carried up and set in the upper, as hereinafter described. A shoulder 191 projects forwardly from the lip 193 and engages the neck ofthe lacing hook at one side thereof for the purpose of removing said lacing hook from the plate 59 when the carrier is rotated, together with said plate 59, from the position illustrated in F ig. 4 to that illustrated in Fig; 5, as hereinafter described.

The general operation of our improved lacing hook setting machine, hereinbefore specifically described is as follows: The lac ing hooks are fed by the picker plate 22 to the raceway 23 and slide down said raceway until the lowermost hook 28 on said raceway rests against the spring stop 29. The raceway, after a few rotations of the picker plate 22, is filled with lacing hooks and is so kept during the operation of the machine. Now, assuming the parts to be in the position illustrated in Fig. 13, which is the position occupied by the parts illustrated in said figure when the machine has come to a stop by reason of the operator removing his foot from the clutch treadle, as hereinbefore described. It will be seen that the anvil, with its feed point, is in a raised position at the right of the lacing hook carrier. The operator places his foot upon the treadle, connected by the rod 144 with the lever 140 and 5 depressing said treadle causes said lever to rock upon its pivot 141, thus raising the presser foot 133, by means of the vertical rod 134. The operator then places the upper beneath the presser foot and releasing the treadle allows the presser foot to descend to the position illustrated in Fig. 13, thus firmly IOO holding the upper 97 pressed against the.

work-support 98. At this point in the operation of the machine, the punch is just ready to descend and the hook carrying plunger is raised to its uppermost position. The combined anvil and punch now descends until the feed point 99 pierces the upper 97 and projects through said upper into the groove 149. The downward motion of the anvil 100 is imparted thereto by the vertical shaft 102, lever 107 and cam 110. The anvil carrier frame, viz, the arm and shaft 102 combined, is next given a rocking movement by the slide 117, link 124, lever 128, cam slide 131 and cam 132, thus feeding the upper from the right toward the left and bringing the feed point 99 into alinement with the lacing hook upon the plate 59. When the feed point has pierced the upper 97 and just prior to the feeding of the upper hereinbefore described, the presser foot 133 is raised by the presser foot lever 140 and cam 143, as illustrated in Fig. 15. After the material has been fed, said presser foot is released by said cam and is brought downwardly to clamp the material against the work-support in the position illustrated in Fig. 12 by the spring 139. The operator, during the feeding of the upper just described, holds the front edge of the upper against the edge gage 150, said ed e gage being located at the proper distance om the groove 149 to locate the hook at the distance desired from the front edge of the upper, and said gage also being located so that the portion which bears against the edge of the upper is in alinement with the feed point when said feed point is at its extreme right hand position, or just as it enters the upper, as illustrated in Fig. 14.

During the time that the anvil and punch are descending, the plunger or hook carrier is moving downwardly from the position illustrated in Fig. 18 to that illustrated in Fig. 14, and this downward movement is imparted to the plunger by the movement of the cam slide 86 toward the right (Fig. 2), said cam slide being actuated by the cam 95. Said plunger is carried downwardly until the plate 59 is level with the lower end of the raceway part 24. During the last part of the downward movement of said plunger and after said downward movement has ceased, the sleeve 66, carrier 62 and plate 59 are rotated in the direction of the arrow (1, from the position illustrated in Fig. 5 to that illustrated in Fig. 4, bringing said plate 59 into contact with the lower end of the raceway part 24, so that said plate forms, in effect, a continuation of said raceway when in the position illustrated in said Fig. 4. During the latter part of this rotary motion, it will be understood that the plunger is stationary as regards vertical movement. This rotary motion is imparted to said sleeve and carrier by the segment lever 45, cam slide 49 and cam 52. At the same time that the carrier 62 is being rotated from the position illustrated in Fig. 5 to that illustrated in Fig. 4, the lowermost lacing hook 28 upon the raceway part 24 is carried by one of the feed dogs 30 past the spring stop 29 around the curved lower end of the raceway part 24 and finally onto the carrier plate 59. The plunger is then carried upwardly and the shank of the lacing hook forced through the upper and clenched there in by the spreading of the shank of the hook upon the anvil 100, the feed point 99 entering the tubular shank of said lacing hook as itis forced through the upper and assisting to guide the same therethrough, as shown in Figs. 8 and 12. s

As soon as the lacing hook has been set, as hereinbefore described, in the upper of the shoe, the anvil 100 rises from the position illustrated in Fig. 12 and moves toward the right to the position illustrated in Fig. 13, ready to descend and feed the upper forward to have another lacing hook set therein. As soon as the anvil and its feed point have moved upwardly a slight distance from the setting position illustrated in Fig. 12, enough to release the pressure upon said hook and upon the carrier plate 59, said carrier and the plate 59 attached thereto are rotated by the sleeve 66 and segment lever 45 from the position illustrated in Fig. 4 to that illus trated in Fig. 5 in the direction of the arrow 6 (Fig. 5), thus clearing the plate 59 from the hook which has been set and leaving the carrier free to descend in order to have a new hook fed thereto, as hereinbefore described.

It will be noted that the rotary movement of the hook carrier 62 and of the feed dogs 30 is simultaneous, both being driven by the segment lever 45, so that as the feed carrier is being moved from the position illustrated in Fig. 5 to that illustrated in Fig. 4, the hook is being fed from the raceway around the lower end of the raceway part 24 and finally onto the plate 59. WVhen the segment lever reverses its direction of motion and the carrier is moved from the position illustrated in Fig. 4 to that illustrated in Fig. 5, the pawl 41 moves over the ratchet 42, engaging a new tooth on said ratchet in readiness for the feeding of the next lacing hook.

As hereinbefore described, if a lacing hook becomes jammed, (through accident or imperfection,) upon the lower end of the raceway or upon the carrier plate 59, the same may be removed by rotating the carrier and its plate by means of the handle 78 from the position illustrated in Fig. 4 to that illustrated in Fig. 5 and then pushing the hook off the raceway or off the carrier plate, as the case may be, the same descending through the recess 63, and cut out passage 7 9 and falling on the floor. The machine is further adapted to automatically clear lacing hooks which are set when no upper is in the machinethat is, if the machine is run beyond the point where the lacing hooks are set in the upper, or if no upper is placed in the ma chine and the operator carelessly starts the same, the lacing hooks would, of course, be fed, as hereinbefore described, onto the plate 59 and carried upwardly and set thereon by the anvil 100. When such a case occurs, the rotation of the carrier and the plate 59, here inbefore described, from the position illus trated in Fig. 4 to that illustrated in Fig. 5 will clear the hook from the plate 59, by reason of said hook coming into contact with the shoulder 191 formed upon the lip 193 of the slide 192 (Figs. 8, 9 and 10), whereby said lacing hook is pushed off the plate 59 and falls downwardly through the passage 79 and out of the machine.

The motions of the different parts, hereinbefore described, are repeated at each rotation of the main shaft of the machine, thus feeding the upper forward and setting lacing hooks therein at equal distances apart as long as the operator keeps his foot upon the clutch treadle. The moment, however, that he removes his foot from the clutch treadle the machine stops in the position illustrated in Fig. 13.

hen it is desired to vary the feed of the upper so as to make less space between the adjacent lacing hooks which are set in said upper the hand nut 127 is loosened and the stud 126 pushed downwardly in the slot 129 from the position illustrated in Fig. 2, bringing said stud nearer the pivotal center 130 of the lever 128 and thus imparting a shorter throw from the lever 128 to the slide 117 and therefore rocking the carrier frame 101 through a lesser angle and feeding the upper a shorter distance than would be the case were the stud 126 located in the upper end of the curved slot 129. The slot 129 being concentric with the pivot 125, when the anvil is in alinement with the lacing hook 77 on the plate 59, such adjustment will not vary the point to which the upper is fed by said anvil and feed point, but will vary the distance at which the feed point enters the shoe upper from said lacing hook 77 on the plate 59 and thus the distance between the lacing hooks will be made greater or less according to the position of the stud 126 in the curved slot 129. The anvil and the feed point will for all lengths of feed of the upper be brought exactly in alinement with the-lacing hook 77 on the plate 59.
